Cybercurrencies are here to stay. Maybe Bitcoin is too, but not at the levels it currently holds. Tulips are still here, but the tulip mania of the 1630s has passed. Bitcoin was originally intended to be a medium of exchange that would be insulated from almost all external control. This anonymity made it an excellent means of exchange for illegal activities, most recently illustrated by the fact that most of the ransomware attacks on private data have demanded payment in Bitcoin.
Bitcoin transactions are recorded by blockchain, which is
like an old accounting ledger. It
contains every Bitcoin transaction, although looking at blockchain from the
outside, you can tell that a transaction is verified, but you cannot tell who
the parties were or how much Bitcoin was involved. As one of the parties to the transaction,
however, you can pull out the specific information. So, if Elon Musk for example says you never
paid him for your Tesla, you can prove that you did using blockchain.
The Economist
magazine recently explored what would happen to the financial markets if
Bitcoin went to zero. It illustrates how
far Bitcoin has come from mainly being a payment mechanism for drug dealers and
other criminals to store of value rivaling gold bullion. Many old school financial institutions --
banks, hedge funds, and payment systems like PayPal -- have begun to invest in and
accept Bitcoin. The Economist speculates
that a Bitcoin crash would also crash the broader financial markets, and the more
widely accepted Bitcoin becomes, the bigger the crash would be. Because there is so much speculation today in
Bitcoin, much of the investment is leveraged, likely leading to margin calls
and liquidations in the event of a Bitcoin crash.
The Economist says that “because changing dollars for
bitcoin is slow and costly, traders wanting to realize gains and reinvest
proceeds often transact in stablecoins” pegged to the dollar, like Tether. The fact that traders think Bitcoin transactions
are slow and costly is ironic, since Bitcoin was conceived as a payment
mechanism. But the reliance on Tether
and other stablecoins creates problems for these currencies, which are somewhat
like money market funds that are vulnerable if they are insufficiently backed,
which many regulators believe they are.
It is ironic that as Bitcoin has become seen as a store of
value, it has become less used as a transaction mechanism, which was its
original purpose. But many Bitcoin proponents
tout Bitcoin as a way for the poor, unbanked people around the world to participate
in the financial system with their wealthier cohorts.
Because of that prospect of some kind of cybercoin becoming
a worldwide medium of exchange, central banks around the world, like the US
Federal Reserve, are looking a creating cybercurrencies that would not have
some of the negative aspects of Bitcoin.
If cybercurrencies become widespread, will that take some of the luster
off of Bitcoin.
Bitcoins will always represent the massive amounts of energy
that were required to produce them. This
unenvironmental aspect of Bitcoin is supposedly what make Elon Musk change his
mind and refuse to accept Bitcoins for Teslas.
If Bitcoin were to go to zero, that would be an awful lot of wasted
energy and greenhouse gases.
Bitcoin will have to find its long-term value. When it was first being mined, it was worth a
few thousand dollars. I would guess that
in the long term, it will return to something like that, less than $10,000 per Bitcoin. It will retain some value as a medium of
exchange for criminals, since national cybercurrencies will be more
traceable. Also, national central banks
will probably be able to print their new cybercurrencies like the Fed now
prints paper dollars, making the new currencies less valuable as a hedge
against inflation.
